Newbie: outputing multiple files

["Swearingen, David W." <dw...@tasc.com>]

I just cranked up velocity and successfully used the #for loop to generate
to stdout several iterations of my template.  

Now I want to put each iteration into a separate file, each file being
auto-named, where the name would be the value of some variable in the
ArrayList I'm iterating.  (I'm generating a bunch of SVG files, each one
with slightly different content.)

It's not clear to me from the docs or examples how to do this.  Help greatly
appreciated.

Cool!

Here's how I would do it.  Note, I'm lazy.  Also note that you cannot and
should not try to fool with the underlying Writer.

Make a little tool that writes to files :

public class Tool 
{
    ... Vars ...

    public void open(String filename)
    {
       ..open file..
    }

    public void write(String stuff )
    {
       .. Write to file...
    }

    public void close()
    {
      ... Yep, close file...
    }
}

Then put one of those in the context.

Next, put the output as a VM :

#macro( mySVG $data )
  ...
#end

And then 

  #foreach($data in $mydata)
      $tool.open($data.filename)
      $tool.write("#mySVG($data)")
      $tool.close()
  #end

And that should do it :)
